Stake with ground engagement feature

ABSTRACT

A ground stake can be easily inserted into the ground and once inserted, the stake includes ground engagement members that can extend out of the stake body to engage into the earth. The ground engagement members, when deployed, can help prevent inadvertent disengagement of the stake from the ground. When the user desires to remove the stake, the user can retract the ground engagement members back into the stake body and easily pull the stake out of the ground for re-use.

BACKGROUND OF THE INVENTION 1. Field of the Invention

Embodiments of the invention relate generally to stakes. More particularly, embodiments of the invention relate to a stake that can be easily placed into the ground and can include ground engagement features to prevent inadvertent release of the stake from the ground.

2. Description of Prior Art and Related Information

The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon.

Ground stakes can be used to create a loop for tying down various items. Ground stakes can be used for securing tents, trees, trailers, storage sheds, or other items that may be affected by wind or other forces that can cause the items to move from their desired location. Ideally, ground stakes should be easy to insert, but more difficult to remove from the ground. To achieve this goal, for example, stakes may be pounded into the ground at an angle, facing away from the device to be secured. However, such positioning can still result in the stake being pulled out or loosened.

In view of the foregoing, there is a need for an improved ground stake that can be easily inserted into the ground, but difficult to inadvertently remove.

It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

In describing the invention, it will be understood that a number of techniques and steps are disclosed. Each of these has individual benefit and each can also be used in conjunction with one or more, or in some cases all, of the other disclosed techniques. Accordingly, for the sake of clarity, this description will refrain from repeating every possible combination of the individual steps in an unnecessary fashion. Nevertheless, the specification and claims should be read with the understanding that such combinations are entirely within the scope of the invention and the claims.

In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be evident, however, to one skilled in the art that the present invention may be practiced without these specific details.

The present disclosure is to be considered as an exemplification of the invention and is not intended to limit the invention to the specific embodiments illustrated by the figures or description below.

As is well known to those skilled in the art, many careful considerations and compromises typically must be made when designing for the optimal configuration of a commercial implementation of any device, and in particular, the embodiments of the present invention. A commercial implementation in accordance with the spirit and teachings of the present invention may be configured according to the needs of the particular application, whereby any aspect(s), feature(s), function(s), result(s), component(s), approach(es), or step(s) of the teachings related to any described embodiment of the present invention may be suitably omitted, included, adapted, mixed and matched, or improved and/or optimized by those skilled in the art, using their average skills and known techniques, to achieve the desired implementation that addresses the needs of the particular application.

Broadly, embodiments of the present invention provide a ground stake that can be easily inserted into the ground and once inserted, the stake includes ground engagement members that can extend out of the stake body to engage into the earth. The ground engagement members, when deployed, can help prevent inadvertent disengagement of the stake from the ground. When the user desires to remove the stake, the user can retract the ground engagement members back into the stake body and easily pull the stake out of the ground for re-use.

Referring now to FIGS. 1 through 8, a ground stake 10 (also referred to as stake 10) can be moved between a deployed configuration (FIGS. 1 and 2) and an insertion configuration (FIGS. 3 and 4). In the insertion configuration, ground engagement members 44 can be retained inside a main stake body 22. In the insertion configuration, the main stake body 22, typically including a pointed tip 46, can be easily inserted or removed from the ground. Once the stake 10 is in the ground, the user can actuate a deployment arm 12, as described in greater detail below, to cause the ground engagement members 44 to extend from the main stake body 22 and into the ground, typically at an upward (toward the surface of the ground, or toward a top surface 26 of the main stake body 22) angle to prevent inadvertent removal of the stake 10 from the ground.

The main stake body 22 can include the top surface 26 with one or more attachment loops 28 formed therein for connecting a rope, cord, or the like. A hole 32 can be formed in the top surface to access an interior of a hollow tubular member 30 of the main stake body 22 that extends downward from the top surface 26. The pointed tip 46 can be attached on a distal end (relative to the top surface 26) of the tubular member 30. In some embodiments, the pointed tip 46 can include male threads 48 that can threadably engage with female threads (not shown) formed at the distal end of the hollow tubular member 30. Typically, the exterior of the hollow tubular member 30 can be generally a smooth surface as shown. However, in some embodiments, exterior undulating protrusions may be formed on at least a portion of the exterior surface, permitting the stake 10 to be screwed into the ground for insertion, for example. The hollow tubular member 30 can have a round cross-sectional shape, as shown, but other cross-sectional shapes, such as rectangular, triangular, or the like, may be used without departing from the scope of the present invention. The hollow tubular member 30 may have a constant cross-sectional diameter, as shown, or may be tapered, as shown in the hollow tubular member of the embodiments of FIGS. 13 through 18, discussed in greater detail below.

The hollow tubular member 30 can include a plurality of ground engagement member openings 34 (also referred to simply as openings 34) into which the ground engagement members 44 can retract into (in the insertion configuration) or extend therefrom (in the deployed configuration). In some embodiments, the openings 34 can include a sloped upper surface 36 to help guide the ground engagement members 44 out of and away from the hollow tubular member 30.

Opposing slotted channels 24 can extend from opposite sides of the top surface 26 of the main stake body 22. The channels 24 can have a length that is at least as long as the movement required for translation of the movable shaft 38, as discussed below, between the deployed configuration and the insertion configuration. A pin 20 can be positioned to span between the channels 24. The pin 20 may travel in the channels 24 between a lower position proximate the top surface 26 (the insertion configuration) and an upper position distal the top surface 26 (the deployed configuration).

The deployment arm 12 can include holes 16 for receiving ends of the pin 20. Thus, movement of the deployment arm 12 (via rotation of the arm extension 14) can move the pin 20 between the lower and upper positions within the channels. The deployment arm 18 can further include a slot 18 formed therein to improve access to the attachment loop 28 when the stake 10 is in the deployed configuration (see FIG. 1).

The pin 20 can extend through a pin hole 40 formed in an upper end of a moveable shaft 38. A lower end 42 of the movable shaft can have the ground engagement members 44 attached thereto. The movable shaft 38 can have the upper end extending out of the hole 32 in the top surface 26 of the main stake body 22. The lower end 42 of the movable shaft 38 is positioned in the hollow tubular member 30, with the attachment loop 56 (discussed in greater detail below) positioned at or near the openings 34 in the hollow tubular member 30 (in the deployed configuration) or below the openings 34 in the hollow tubular member 30 (in the insertion configuration). The movable shaft 38 can be moved between the insertion configuration and the deployed configuration via movement of the arm extension 14 of the deployment arm 12, causing the pin 20 to move along the channels 24, thus raising or lowering the movable shaft 38.

In the insertion configuration, the ground engagement members 44 can be positioned inside the openings 34 in the hollow tubular member 30. Typically, distal ends of the ground engagement members 44 (distal relative to their attachment slot 54) can rest against the sloped surface 36 of the openings 34, thus urging the ground engagement members 44 out of the openings 34 as the stake is moved into its deployed configuration.

Referring also to FIGS. 9 through 11, the ground engagement member 44 may be formed as a flat, elongated member that can include a sharpened tip 52 to help ground penetration when deploying the stake in the ground. The ground attachment members 44 may pivotably attachment to the distal end of the moveable shaft 38. Various attachment mechanisms may be used to provide this pivotable attachment. For example, an attachment slot 54 can be formed in an attachment end of the ground engagement member 44. The attachment slot 54 can be removably attached into an attachment loop 50 formed at the distal end of the moveable shaft 38.

While two ground engagement members 44 are shown extending from openings 32 on opposite sides of the hollow tubular member, it should be understood that any number of ground engagement members 44 may be used, depending on their size and the desired application. For example, three or four ground engagement members 44 may extend from the stake in the deployed configuration. The embodiment shown in FIGS. 13 through 18 illustrate four ground engagement members, as discussed in greater detail below.

Further, two or more ground engagement members may be disposed within a single opening 32 so that two or more ground engagement members may be released outward from a single opening 32. In this embodiment, the ground engagement members may have a resilient curvature that can cause the ground engagement members to move away from each other as they are deployed.

Further, it should be noted that, as illustrated, the openings 32 are positioned at a single height from the pointed tip 46. However, the openings 32 may have an offset height. In some embodiments, a long hollow tubular member may be used with the ground engagement members 44 extending from more than one height from the pointed tip 46. As shown in FIG. 12, a first set 44A of ground engagement members 44 may extend from an upper height from openings 32 and a second set 44B of ground engagement members 44 may extend from a lower height from the openings 32. Such a configuration may be useful in soft ground or where additional holding strength is desired.

Referring now to FIGS. 13 through 16, a stake 60 can include a hollow tubular member 62 (also referred to as outer cover 62) having two or more slotted openings 64 disposed along a length thereof. Typically, the slotted openings 64 are disposed on different sides of the hollow tubular member 62 at the same height therealong. For example, four slotted openings 64 are shown disposed along the outer cover 62 at 90 degree intervals about the conical tubular member 62, as shown in the figures. While a conical hollow tubular member 62 is shown, this element may have a constant cross-section, similar to the hollow tubular member 30, described above. A pointed tip 68 can be formed at the bottom of the hollow tubular member 62 to aid in insertion of the stake 60 into the ground.

A movable member 70 can extend from an opening in the top of the hollow tubular member 62 and move between an insertion configuration (FIG. 13) and a deployed configuration (FIG. 15), where, in the deployed configuration, the movable member 70 extends out from the opening in the top of the hollow tubular member 62 a distance farther than when in the insertion configuration.

A loop 72 can be formed on the top of the movable member 70. The loop 72 can be used to move the movable member 70 upward into the deployed configuration. Once in the deployed configuration, the loop 72 can be used as a tie down loop for a rope or the like.

A ground engagement member 74 can be attached to the bottom end of the movable member 70. The ground engagement member 74 can be formed from a first arm 74A having its top end 86 attached to the hollow tubular member 62 so as to pivot about an axis 82. A second arm 74B can have its bottom end 84 attached to the bottom end 88 of the movable member 70. The top end of the second arm 74B and the bottom end of the first arm 74A can connect at a pivoting joint 80.

In use, the stake 60 can be inserted into the ground and the movable member 70 can be moved upward, changing the stake from being in the insertion configuration to the stake being in the deployed configuration, with the ground engagement members 74 moving into the earth outward from the hollow tubular member 62. As the movable member 70 is moved upward, the top end 86 of the first arm 74A is vertically fixed (via its pivoting attachment axis 82 onto the hollow tubular member 62), with the pivoting joint 80 (connecting the arms 74A and 74B) moving outward (as the angle formed from the pivoting joint 80 changes from about 130 to 180 degrees (in the insertion configuration) to about 20 to 60 degrees (in the deployed configuration).

Referring now to FIG. 17, the top of the hollow tubular member 62 may include an extended plate 78 that may be placed flat against the ground after insertion of the stake 60. The user may use the extended plate 78, for example, to secure the stake in place while the movable member 70 is raised to engage the ground engagement members 74. A user, for example, can step on the extended plate 78 to prevent removal of the stake while raising the movable member 70.

A loop 76 may be formed on the extended plate 78. The loop 76 may be used as a tie down or as a pull tab for removing the stake after use thereof and after moving the movable member 70 back to the insertion configuration (with the ground engagement members 74 moving back within a periphery defined by the outer surface of the hollow tubular member 62), permitting removal without having to pull on the movable member 70 (and possibly re-deploying the ground engagement members 74).

Referring now to FIG. 18, in some embodiments, a stopper 90 may be formed on the movable member 70. The stopper 90 can be configured to rest against a top inner surface of the hollow tubular member 62 when the movable member 70 is in the deployed configuration. The stopper 90, when the stake is in the deployed configuration, can also act to keep dirt or debris from entering a space between the opening in the top of the hollow tubular member 62 and the movable member 70 when the stake is deployed, thus preventing such dirt from causing difficulties in moving the stake back to the insertion configuration when the user desires to remove the stake from the ground after use.

In the embodiment of FIGS. 13 through 18, the bottom of the ground engagement members 74 are attached to the movable member 70, while the top of the ground engagement members 74 are attached to the inside of the hollow tubular member 62. The opposite connection can also be used. For example, in some embodiments, the top of the ground engagement members 74 can be attached to the movable member 70, while the bottom of the ground engagement members 74 are fixed to the inside of the hollow tubular member 62. In this embodiment, the ground engagement members 74 can extend to the deployed position by pushing the movable member 70 down after the entire assembly has been inserted into the ground (instead of pulling it up, as in the embodiment of FIGS. 13 through 18). This would require the loop to be on the hollow tubular member 62 to secure a rope or the like, but this embodiment can enable the expansion to be lower in the ground, and would not requiring holding the unit down while pulling up on the movable member 70 to deploy. To insert into the ground, the movable member 70 would be extended up first (to have the ground engagement members 74 in the insertion configuration), and the outer plate of the hollow tubular member 62 would be used to insert the unit into the ground.
